Sync to Furthest Page Read: Our Whispersync technology automatically syncs your books across apps, so you can start reading on one device with the Kindle app installed, and pick up where you left off on another device with the Kindle app installed. You don’t need to own a Kindle to use the app, but if you do, Whispersync also syncs your Kindle books between your apps (including the Kindle for PC app) and your Kindle devices.
